Title: Obstacke detector for vehicle
Inventor: HAYASHI MASAYUKI
IPC: B60R21/00
Filed: 1986-07-22
Abstract: PURPOSE:To promote the removal of an obstacle and to prevent the erroneous operation of an ultrasonic sensor, in such a case that the adhesion or freezing of snow or water is generated in an ultrasonic sensor horn, by rapidly detecting this state to inform the same to a user. CONSTITUTION:When an obstacle such as snow is present in a sensor horn, an ultrasonic wave is reflected and converted to an electric signal by an ultrasonic transmitter-receiver 4 while said electric signal becomes an H-level signal IV through an amplifying circuit 5, a band-pass filter 6 and a wave-form shaping circuit 7 to enter an AND gate 9. Said signal IX, the gate signal IV(H-level) in the sensor horn and a change-over signal I(L-level) enter the AND gate 9 to output an H-level signal XI. The sensor horn, that is, a display circuit 11 receives the signal XI to output a definite time signal and a display lamp lights. As mentioned above, by informing that foreign matter is adhered to the interior of the ultrasonic sensor horn to a user, a period having to remove the foreign matter is shown and, by this method, the erroneous operation of an ultrasonic sensor is prevented.

Title: Method and apparatus for ultrasonic flaw detection
Inventor: YAGI TAKESHI
IPC: G01N29/28
Filed: 1985-08-07
Abstract: PURPOSE:To attain to enhance the efficiency of flaw detection work, by arranging a plurality of probes so as to contain the entire surface of a material in a flaw detection range and linearily moving the material. CONSTITUTION:A probe 2 is contacted with a material 10 at the outer peripheral position thereof through an appropriate medium. When ultrasonic beam is allowed to be incident to the material 10 along an incident ling PO-PQ by the probe 20, the ultrasonic beam gradually expands to be spread in the region surrounded by a line PO-PR and a line PO-PS. At this time, when a flaw is present on the circular arc PR-PS of the material 10, a flaw echo appears in the incident ultrasonic beam and the detection of the flaw can be performed by this method. Therefore, when the length of the circular arc PR-PS is set to (l) and the diameter of the material 10 to (d), an integer (n) exceeding pid/l is calculated and, if (n) or more probes are arranged on the periphery of the material 10, flaw detection can be performed over the entire periphery of the material 10 without rotating the material or the probe. By this method, the efficiency of flaw detection work can be enhanced.

IPC: G11B5/09
Filed: 1993-06-18
Abstract: PURPOSE:To improve the probability correctly reading the data by lowering a running speed of a magnetic tape when an error is detected and rereading the data. CONSTITUTION:This device is provided with a tape running motor 15 for running the magnetic tape 5 recording the data, a magnetic head 16 for reading the data from the tape 15 and a CRC circuit 30 for detecting the error in the data obtained from the head 16. When the tape 5 runs forward at a first speed, and the data are read, if a signal showing the error occurs from the CRC circuit 30 for detecting the error, the tape 5 is rewound so as to incorporate an area where the error is detected. Then, the tape 5 is driven forward at a second speed (preferable speed lower than the first) different from the first speed while controlling by a control means constituted of a motor 15, a driving roller, a CPU 19, etc. Thus, the fact that the data not read until then is read occurs often, and thus, the data are read correctly.

Abstract: PURPOSE:To obtain perovskite-type ceramics powder without containing a large amount of oxygen defects, by thermally decomposing a complex or mixed metallic oxalate, pulverizing the resultant decomposition product and calcining the obtained powder in the an atmosphere under a specific oxygen partial pressure. CONSTITUTION:A complex or mixed metallic oxalate to provide perovskite-type ceramic powder by thermal decomposition calcining is thermally decomposed, then pulverized and subsequently calcined in an atmosphere under >=0.25 oxygen partial pressure. A complex or mixed metallic oxalate normally synthesized by a wet process can be employed as the complex or mixed metallic oxalate used and may be a substance capable of providing the aimed perovskite-type ceramic powder by calcining. The total pressure in a furnace in calcining is preferably >=1atm. If the oxygen partial pressure is below 0.25, oxygen defects of the perovskite-type crystal cannot be corrected. If the partial pressure exceeds 0.8, especially great effects on characteristics cannot be expected and it is not advantageous in aspects of safety and economics.

Title: Magnetic recording and reproducing device
Inventor: AOKI JUNICHI
IPC: H04N5/95
Filed: 1992-06-30
Abstract: PURPOSE:To obtain a superior image without switching noise in which skew is eliminated with simple processing. CONSTITUTION:A 2nd signal obtained from a head B by a delay line 3 is more delayed than a 1st signal obtained from a head A. The 1st signal and the 2nd signal are synthesized by a switching circuit 4 and the resulting signal is demodulated by a demodulation circuit to obtain a video signal. On the other hand, a head switching pulse from a servo system is latched by a flip-flop 8 at a timing of a horizontal synchronizing signal obtained from the video signal after demodulation and the switching circuit 4 obtains a pulse selecting the 1st and 2nd signal. A write-off signal is generated by a write-off signal generating circuit 10 based on the pulse and a signal latching the pulse in a timing of a horizontal synchronizing signal. The write signal stops the write to a memory 12 of a time axis correction circuit 16 and a duplicated part caused in the video signal due to the delay of the 2nd signal is eliminated.

Abstract: PURPOSE:To prevent a load from malfunctioning due to a reduction in power by bringing the operation of a switching circuit into coincidence with the power supply starting time of an inverter at the time of interruption of an AC power source or voltage drop. CONSTITUTION:If a power interruption or a voltage drop occurs in an AC power source, a power interruption detector 14 detects it, and transmits a signal to a switching circuit 13. Thus, the relay 13A of the circuit 13 is shifted to a second contact (b). Accordingly, an inverter 12 converts the DC output of a storage battery 15 to an AC output and supplies it to a load. When the circuit 13 is shifted to a second contact (b), the inverter 12 is immediately set to supply a total output having a pulse width necessary to drive the load to the load. That is, the time point of switching from the AC power source to the inverter 12 is brought into coincidence with the rise starting point of the output of the inverter 12 and can supply an AC output having a pulse width necessary to drive the load.
